Radiography & ScanningRadiation, MRI, and CAT scanning suites include a variety of viewing tasks. Two key areas are the equipment and scanning room and the imaging and viewing room. Generally, the equipment and hardware operates in a vertical or horizontal plane so placement and shielding of luminaires is critical to avoid glare to the patient’s eyes.
Use high (>85) CRI general light sources to provide high quality flattering light for patient comfort and appearance.
Dimming and switching controls are needed to adjust illuminance levels for patient transfer and prep, equipment operation and room cleaning and servicing.
Portable task lighting may be needed for catheterization.
Backlit ceiling graphics or patterns of light projected on ceiling create visual interest and distraction
Viewing room lighting should follow the guidelines for visual display screens in offices (IES RP-1-04 American National Standard Practice for Office Lighting)
Specialized analytical equipment and personal computers are in constant use. For general illumination, easily sterilized direct and indirect luminaires with lenses or louvers will minimize glare on display screens. High color temperatures and excellent color rendering are essential in general and task light sources for viewing cultures, blood and tissue samples. Portable or ceiling task lighting is needed to provide oblique illumination for venipuncture procedures. e.g. blood banks and dialysis labs.
Non Clinical Support Areas
Reception areas and waiting room, in particular, convey the image of the entire hospital. In the waiting areas people may be tense, anxious or in pain. The lighting can help provide a calming environment, as well as a feeling of cleanliness and hygiene to instill trust. Above all the lighting solutions for circulation areas and waiting rooms should be designed around the patient. General lighting should be more indirect than direct and be reflected off ceilings and walls. Dimmable wall lighting and free-standing or table luminaires will radiate a relaxing ‘homelike’ ambience. Where architecturally feasible, dynamic daylighting systems provide a positive connection to the outside world.
There are many other non clinical support areas in a healthcare facility, each with their own lighting design needs. These include:
Architectural exteriors and signage
Parking lots and garages
Entrance lobbies and circulation areas
For the most part, the lighting system goals are the same as those in other commercial buildings. These are covered in other application areas on SYLVANIA.com (Office Lighting, Retail Lighting, Hospitality Lighting, Street & Roadway Lighting) as well as a variety of IESNA technical publications.
